java.lang.IllegalStateException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • After having switch to spring-data-mongodb 1.4.1.RELEASE, we experience a {{Detected mapping ambiguity! String document cannot be mapped to more than one type!}} exception during the startup of the Spring context. There was not problem with 1.2.0.RELEASE before. I attached a small Maven project with 4 classes to reproduce an issue. The unit test needs a valid connection to MongoDB. The problem occurs when using a class with a generics parameter. The class itself is not a document - just a class with {{@TypeAlias}} annotation. The class is used by two other classes, which are MongoDB documents. The framework discovers the class with a generics parameter twice and adds it to the list of persistent entities in {{AbstractMappingContext}} each time with a different TypeInformation. As a workaround we patched {{MappingContextTypeInformationMapper}} class to extract always {{ClassTypeInformation}} from the given entity type and to store this {{ClassTypeInformation}} in a {{HashMap}}. The exception stack trace is: {noformat} java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.CacheAwareContextLoaderDelegate.loadContext(CacheAwareContextLoaderDelegate.java:99) at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:122) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:109) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.prepareTestInstance(DependencyInjectionTestExecutionListener.java:75) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:307) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:211) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:288) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:284) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:88) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.junit.runner.JUnitCore.run(JUnitCore.java:157) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:74) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:211) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:67) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mappingConverter': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.data.mongodb.core.convert.MappingMongoConverter]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: Detected mapping ambiguity!
